Application fi'led December 9, 1926. Serial No. 153,652.

The present invention relates to road scraper or shaver for smoothing dirt, top soil, or other comparatively soft surface roads and the object of the invention is to provide a structure which operates upon the principle of shearing practically parallel to traffic rather than the bouncing method of the blade of the usual roa'd scraper which is disposed.almost perpendicularly to traffic and leaves a transversely corrugated road surface.

Another important object of the invention lies in the provision of a device of this nature which is simple in its construction. thoroughly eflicient and reliable in use, strong and durable, inexpensive to manufacture and otherwise Well adapted-to the purpose for which it is designed.

Vith the above and numerous other obj ectsin view as will appear as the description proceeds, the invention resldes in certain novel features of construction, and 1n the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: Figure 1. is a top plan view of the device embodying the features of my invention,

Fig. 2 is a side elevation thereof, Fig. 3 is a rear elevation thereof, Fig. 4 is a longitudinal section therethrough taken substantially on the line 4-4.

of Fig. 1,

Fig. 5 is a perspective View of one of the blades,

Fig. 6 is a fragmentary sectional rear ele- I vation of another embodiment of the invention, y

Fig. 7 is a perspective view of another em bodiment of the blade.

Referring to the drawing in detail, and particularly to the preferred embodiment of the invention shown in Figures 1 to 5 inclusive, it will be seen that the scraper includes a plurality of longitudinally extending blades A co-extensively arranged one along side of the other in spaced relation and a pair of side blades B which extend a distance to the rear of the blades A. Each blade includes an elongated web 5 having top and bottom flanges 6 which taper towards the front and merge into a rounded front edge of the web 5. These flanges are preferably corrugated as is'indicated at 8, said corrugations being disposed at the forward ends of the flanges, each corrugation extending transversely thereof. Apertures 10 are provided in the forward ends of the blades and are pierced by a rod 11 having spacing elements 12 thereon for holding the forward ends of the blades in a predetermined spaced relation. The rear ends are slightly spaced from one another. A cross bar 14 has its ends hinged to the rear ends of the blades B as denoted at 15 so as to allow a certain side play at the rear end of the device. The rear ends of the blades A are free. An inverted U-shaped rod 1.6 has its extremities piercing openings in the flanges 6 at the top rear portions of the blades 13 so that the bight of the rod 16 eX- tends over the rear free ends of the blades A to limit the upward swinging movement thereof as is clearly indicated in dotted lines in Fig. 2 in order to prevent portions of the free rear ends of the blades A from overlapping or becoming caught one in another I provide plates 18 extending between adjacent edges of the flanges 6 at or adjacent their rear ends.

The blades A and B may be made each of an integral formation being cast in the formation shown or machined from I beams. However, other embodiments may be utilized to advantage such as the embodiment shown in Fig. Twherein an elongated web 5 may be constructed of wood or the like and has metal forwardly tapering flanges 6 on its upper and lower edges, said flanges having their forward portions corrugated as at 8'. In this embodiment of the invention the rear end of the web 5 is formed with a laterally extending head 18 terminating flush with the adjacent edges of the flanges 6 to function in the same manner as plate 18 heretofore referred to. The forward rounded edges 7 are substantiallyfeathered edges for cutting purposes. The corrugations tend to scrape the roadway while the remaining portions of the flanges function as drags. The forward ends of the side blades B are provided with arcuate series of apertures 20 with which clevises or the like may be engaged for the purpose of towing the device in connection with a wagon, truck, tractor, or any other suitable draft means. The width, length, weight, and materials and the frame style do not form the essence of this invention and may be varied to suit the circumstances of the user. The blades are reversible as will be apparent so that when the lower flanges wear the blades may be individually reversed 18 or equivalent means and use instead pins bar 16 to the other side as will bequite ap-' parent. I The depth at which the device-will tend to dig is governed by the apertures 20 into which the clevises or the like are put as will also be apparent, In Figure 6 I have shown an embodiment of the invention which maybe used to advantage wherein I eliminate the plates 21 projecting upwardly from therear ends of the. blades A-and piercing openings 22 in rod 16 which is similar to red 16 hereinbefore referred to. These pins 21 will tend toniaintain the rear ends of the blades A at an approximate equal spaced relation.

By dragging this device along the road with; a suiiicient number of blades all run- .ning parallel tov trafiic, the road may be smoothed, sheared, and tracked and no cross ridges will be formed. The frame structure may be made for a drag of wagon type or motor propelled machine, but of course, I =do not desire myself to be limited to any paiticular draft means. i r

l o It is tl oughtthatthe construction, utility, and advantagesof this inventionwill now be'apparengt to, those skilledin this art without n'iore detailed description thereof.

" 'lfhe present embodiments of the invention have been disclosed in detail merely by way examples, since in actual; practice they attain the features of advantage enumerated as desirable in the staten'ient of the invention.

and the. above description. It will be apparent that changes in the details of construction, in tl e'sizes, in the materials, and in the coinresorted to without departing from the spirit'or scope of the invention as hereinafter claimed or sacrificing any of'itsacb vantages.-
